New York Yankees manager Aaron Boone enforces one necklace rule for outfielder Alex Verdugo.

New York Yankees manager Aaron Boone has introduced a rule for new outfielder Alex Verdugo, limiting him to wear one necklace, or chain, per game. Verdugo, who previously played for the Boston Red Sox, was known for frequently wearing multiple gaudy chains. The Yankees have a strict appearance policy in place since 1976 that limits hair length and bans facial hair besides mustaches.
